To whiten teeth with banana peel is very safe and healthy for teeth as banana peels are a wonderful source of minerals and vitamins. They do not have the abrasiveness that other natural whiteners have and best of all they are inexpensive.
brush your teeth as usual with a natural toothpaste or you can use the banana peel first and then brush.
Take a piece of the inside of the banana peel and gently rub around on your teeth for about 2 minutes.
The amazing minerals in the peel like potassium, magnesium and manganese absorb into your teeth and whiten them.
